Atypical retardation patterns in scanning laser polarimetry are associated with low peripapillary choroidal thickness.
PURPOSE Scanning laser polarimetry (SLP) results can be affected by an atypical retardation pattern (ARP). One reason for an ARP is the birefringence of the sclera. The purpose of this study was to investigate the influence of the peripapillary choroidal thickness (pChTh) on the occurrence of ARP. METHODS One hundred ten healthy subjects were investigated with SLP and spectral domain OCT. pCh...
متن کاملEnhanced corneal compensation for scanning laser polarimetry on eyes with atypical polarisation pattern.
AIM To investigate the potential advantage of an enhanced corneal compensation algorithm (ECC) compared with variable corneal compensation (VCC) in the analysis of scanning laser polarimetric (SLP) images with atypical retardation pattern (ARP). METHODS SLP-VCC images with ARP (typical scan score (TSS) <80) of one eye of each of 27 glaucoma patients and 19 healthy subjects were compared with ...

PURPOSE To determine the correlations and strength of association between different imaging systems in analyzing the retinal nerve fiber layer (RNFL) of glaucoma patients: optical coherence tomography (OCT), scanning laser polarimetry (SLP) and confocal scanning laser ophthalmoscopy (CSLO). MATERIALS AND METHODOLOGY 114 eyes of patients with moderate open angle glaucoma underwent spectral dom...
متن کاملDetection of glaucoma with scanning laser polarimetry.
OBJECTIVE To determine which retinal nerve fiber layer (RNFL) measures obtained with scanning laser polarimetry are most useful in detecting early to moderate glaucomatous visual field loss. SUBJECTS AND METHODS One eye from 84 healthy individuals and 83 patients with early to moderate glaucomatous visual field loss (167 eyes) was assessed with a scanning laser polarimeter (Laser Diagnostic T...
متن کاملQuantitative assessment of atypical birefringence images using scanning laser polarimetry with variable corneal compensation.
PURPOSE To define the clinical characteristics of atypical birefringence images and to describe a quantitative method for their identification. DESIGN Prospective, comparative, clinical observational study. METHODS Normal and glaucomatous eyes underwent complete examination, standard automated perimetry, scanning laser polarimetry with variable corneal compensation (GDx-VCC), and optical co...
